Stunning: The beautiful brunette actresses looked stunning in their white dresses at the Gravity premiere

Just the two of us: George Clooney and Sandra Bullock are the only two actors in their new movie Gravity, which sees them play a pair of astronauts who get stranded in space

The gorgeous actresses weren’t the only celebrities in attendance at the premiere, which took place at AMC Lincoln Square Theater.

Sandra was joined by her Gravity co-star George Clooney, who looked as handsome as ever in a dark suit, white shirt and dark tie.

Sandra and George are the sole actors in the new film directed by Alfonso Cuarón, in which they star as two astronauts stranded in space after being battered by the floating debris from a destroyed Russian satellite that has ruined their shuttle.

Bullock plays rookie Dr Ryan Stone, to Clooney's veteran astronaut Matt Kowalsky, who must navigate their way across the void of space to reach the international space station and their only chance of salvation.

Never forget: Although George has tried to put his much derided turn as Batman behind him, he gamely signed a poster for a fan at the premiere

While George has previously starred in the space thriller Solaris - the Steven Soderbergh remake of Tarkovsky's sci-fi classic - Gravity is tipped as one of the most tense action thrillers of the year.

Cuarón first eyed Robert Downey Jr. and Angelina Jolie for the lead roles, but Jolie turned the project down in September 2010, followed by Natalie Portman, who also decided against making it, leading Bullock to take the part.

Downey Jr. left the film in October 2010 due to scheduling conflicts, and Clooney took over the role in December that year.

Much like Tom Hanks' turn in Castaway, Bullock is onscreen by herself for much of the film.

Sandra recently called Gravity the ‘best life decision I ever made’.

She explained: ‘What I got out of it personally outweighed everything else. I'm glad I got to meet the human being -- Alfonso -- that led me to say, “OK, let me investigate if I can even do this.” ’

However, she only agreed to take it on if she could have her now three-year-old son Louis with her on set.

She recalled telling the director: ‘It has to be a great time for my son. I can't miss him. If I miss him, I will be of no use to you. 'You know, he's just learning how to walk. So guess what's going to happen? I have to go! He's taking steps!’

Support: Actresses Carla Gugino and Katrina Bowden also showed their support for Gravity

And her concerns were met: ‘They made it so (nice for Louis). It was a family film. Everyone had kids.

So everyone knew the value of that. So they said, “If we make it amazing for him right where you are, will you be OK?” And I said, “yeah”’.
